Income Tax Calculator

Use this free Income Tax Calculator to estimate your federal tax liability and rate. Simple, accurate, and easy to use for tax planning.

It's not what you make, it's what you keep. The Income Tax Calculator estimates your federal tax liability and your effective tax rate. Understanding these numbers is crucial for accurate budgeting and preventing "tax surprise" in April.

The US tax system is progressive, meaning you don't pay one flat rate on all income. This calculator navigates the tax brackets to show you how each slice of your income is taxed.

When to Use This Calculator

Use the Income Tax Calculator to:

  • Estimate Withholding: Ensure your employer is withholding the correct amount from your paycheck.
  • Windfall Planning: "If I sell this stock or get a bonus, how much will go to taxes?"

Example Scenario

You are single and earn $60,000 taxable income.

You don't pay 22% on the whole amount.
- First ~$11k is taxed at 10%.
- Next ~$33k is taxed at 12%.
- Only the remaining ~$15k is taxed at 22%.

Your Effective Tax Rate might be closer to 15%, which is much lower than your top bracket.

Marginal vs. Effective Rate: Your marginal rate is the tax on your next dollar earned. Your effective rate is the average percentage you pay total.

Common Mistakes

fearing the "Next Bracket": Earning more money never results in less take-home pay. Only the extra money is taxed at the higher rate.
